2 GRIFFON VULTURE 



only did we find an egg and a young one in the same nest ; 

 in all other cases, one egg or one young one was the invari- 

 able number. The eggs appear to be laid in the month 

 of February, as most of the nests contained young in the 

 beginning of April. During the time of incubation, one 

 of the parent birds sits constantly, and, if frightened off, 

 returns immediately. The nest is composed almost entirely 

 of sticks, which are used in greater or less abundance, as 

 the situation requires. 



" The eggs obtained from wild birds generally show in- 

 dications of natural colouring, in addition to the blood and 

 dirt with which they are usually stained. This colouring is 

 dispersed in faint spots of a reddish hue, sometimes all over 

 the egg, but generally at the larger or smaller end."
